Species Description
The Grey-headed Albatross, also known as the Grey-headed Mollymawk, is a large seabird that nests on several islands in the Southern ocean. While breeding, they forage within or south of the Antarctic Polar Frontal Zone, the area surrounding Antarctica where cold waters meet relatively warmer waters of the subantarctic. Young birds and non-breeding birds fly and forage freely throughout all southern oceans. The Grey-headed Albatross feeds primarily on squid, while also on fish, crustacean, and carrion. They can dive seven meters deep to hunt prey. The Grey-headed Albatross weighs approximately 3.65 kilograms. It has a dark grey head and neck, black wings, back, and tail, and white breast. One of its most distinguishing features is its black bill with bright yellow ridges. The species is classified as vulnerable on the IUCN Red List—the decline in populations is mainly owing to mortality on longline fisheries.
